Abstract A method for compensating cooking time of a microwave oven which sets an exact reference voltage and automatically controls cooking time in accordance with variation of an input voltage, includes the steps of: setting the reference voltage based on the input voltage regulated to a rated voltage in a state that power is applied or a load is driven and storing the reference voltage in a memory; checking a level of a currently input voltage; and calculating compensating time in accordance with a difference value between the currently input voltage and the reference voltage. Thus, it is possible to minimize dissatisfaction of a user due to voltage variation.
